US Tactical Supply is offering the SUPCOV suppressor cover. The SUPCOV is a low-profile composite material cover that slips over a suppressor to mitigate mirage by more effectively combating heat build-up and dissipating it more effectively. The US Army is requiring a similar device for the CSASS program.

Covers are available for a variety of suppressors including purpose-built covers for the M110 and covers that can be cut to length for common 1″, 1.5″, & 2″ diameter suppressors. Covers are typically available in black of Coyote.

Covers retail from $35 to $55.
